The Knicks have been lacking everywhere this season. Undoubtedly in wins. Definitely in talent. And now, according to Courtney Lee, undeniably in effort. “When you watch film, it’s just all effort,” Lee said Monday after practice in Tarrytown, his first non-game work with the team in nearly a week following a death in the family. “Effort is the key to everything. It takes no talent to run from the paint out to contest a 3-point shot, that’s just all effort. We have to get everybody’s effort. Everybody’s got to be locked in.”
